Canister assembly for a cryopreservation container

Abstract

The present invention refers to a canister assembly (1) suitable for a cryopreservation container comprising: a rigid elongated handle (2) having a hook (3) in the upper part (4) suitable for supporting said rigid elongated handle (2) in an a cryopreservation container (13), a thermal bridge (5) in the upper part (4) of said elongated handle (2) and a lower portion (6); at least two cylindrical cups (7,8) having a series of apertures (12) in the bottom side, in which said at least two cylindrical cups (7,8) are located one on top of the other sharing the same longitudinal axis, and being attached to said lower part (6) of said rigid elongated handle (2); being separated by a supporting member (9) attached in a fixed manner to the upper cylindrical cup (7); characterized in that the bottom cylindrical cup (8) is attached in a fixed manner to the lower part (6) of the handle (2) by fixing means (11) and the upper cylindrical cup (7) comprises non-slip pivot joints (10) suitable for rotating the upper cylindrical cup (7) around the handle's (2) axis.

1 . A canister assembly suitable for a cryopreservation container comprising:
 a rigid elongated handle having a hook in the upper part suitable for supporting said rigid elongated handle in a cryopreservation container, a thermal bridge in the upper part of said elongated handle and a lower portion;   at least two cylindrical cups having a series of apertures in the bottom side, in which said at least two cylindrical cups are located one on top of the other sharing the same longitudinal axis, and being attached to said lower part of said rigid elongated handle; being separated by a supporting member attached in a fixed manner to the upper cylindrical cup;   wherein the bottom cylindrical cup is attached in a fixed manner to the lower part of the handle by fixing means and the upper cylindrical cup comprises cylindrical joint means suitable for rotating the upper cylindrical cup around the handle's axis.   
     
     
         2 . The canister assembly according to  claim 1 , wherein the upper part of the rigid elongated handle is attached to the lower part of the rigid elongated handle in a “Y” form. 
     
     
         3 . The canister assembly according to  claim 1 , characterized in that the upper part of the rigid elongated handle is attached to the lower part of the rigid elongated handle in a straight form. 
     
     
         4 . The canister assembly according to  claim 1 , wherein said canister assembly has two or three cylindrical cups. 
     
     
         5 . The canister assembly according to  claim 4 , wherein said canister assembly has two cylindrical cups. 
     
     
         6 . The canister assembly according to  claim 1 , wherein said supporting member comprises a translation blocker surface. 
     
     
         7 . The canister assembly according to  claim 1 , wherein said supporting member comprises a rotation locker surface ( 15 ). 
     
     
         8 . The canister assembly according to  claim 1 , wherein said bottom cylindrical cup has at least one cylindrical joint mean ( 10 ). 
     
     
         9 . The canister assembly according to  claim 1 , wherein the canister assembly is made of any material resistant to LN 2 . 
     
     
         10 . The canister assembly according to  claim 1 , wherein the canister assembly is made of stainless steel. 
     
     
         11 . Use of the canister assembly according to  claim 1  for storing of biological samples in a container for cryopreservation. 
     
     
         12 . Use, according to  claim 11 , wherein said biological sample is selected from the list comprising stem cells, special cells for transfusion like platelets, blood, histological samples and animal biological material, as well as reproductive samples, such as sperm, embryos and fertilized eggs.
